BARREL-SCALES.

SPECIFICATION forming part of Letters Patent No. 258,287, dated May 28,1882.

Application filed August 6, 1881.

To all whom it may concern Be it known that I, JOHN DOLPH, of Bay Uity,inthecountyOfBay and StateofMichigan, have invented an Improvement in Scales, of which the following is a specification.

The nature of this invention relates to certain new and useful improvements in the construction of scales which are especially designed to be employed in the filling of salt or other barrels and to determine the quantity which the barrels shall contain.

In the scales heretofore employed the platform often becomes bound aga-inst the frame within which it has its movement, and thereby hindering the effective workin g ofthe scale; and the Object of this invention is to so hang the platform as to Obviate this difficulty; and to that end the invent-ion consists in the peculiar construction, arrangement, and combination of the parts, all as more fully hereinafter set forth.

In the accompanying drawing, which forms a part of this specification, and in which my invention is shown in perspective, A represents a suitable frame to support the operatin g parts Of the scale, and which may be mounted upon suitable rollers or casters, it' desired, so that it may be readily moved from place tO place.

B represents the beam ofthe steel yard-scale, which may be graduated and provided with an adjustable weight, O, which may be secured to the position upon the beam by means of a setscrew, b. Pendent from the shorter arm of this beam by means of a suitable hanging is the frame D,tO the lower end of which is rigidly secured the platform E. At or near the four corners of this platform are rigidly secured the eyebolts d, with which is engaged one end of the rods F, the opposite ends of which are properly secured to the lower portion of the frame A, they being arranged in such a manner as to hold the platform E free from and (No model.)

to prevent its coming into Contact with the frame at any point in its vertical movement during the process of weighing.

It will be seen by this construction that the Objections raised against the Old style of scales are entirely avoided, and that the barrel may be filled with salt or other material to the exact weight determined by the position of the weight upon the lever, as the platform can in no way become bound within the frame.

I am aware that platform-scales have heretofore been supplied with stay-rods to prevent the platform from becoming bound; but the platforms of such scales have a very limited movement, and therefore the stay-rods as used in said scales would not answer with my steelyard-scale, Owing` to the greater movement of my platform. My scale being especially adapted for weighing barrels containing salt or other weighty substances,it is very desirable to have the platform as near the iioor as possible, in order to facilitate the movement of the barrels to and from the platform, and by attaching the brace-rods to the frame and platform above the platform, as shown in the drawing, I am e11- abled to bring the platform much nearer to the iioor than by any other arrangement of said brace-rods.

What I claim as my invention is- In a portable scale, the platform E, the steelyard B, and the bifnrcated yoke D, connecting the platform audsteelyard,in combination with the frame A, supporting'the steelyard and provided wit-h a base surrounding three sides of the platform, and the four stay-rods F, connected to four sides of the upper surface of the platform and to the three sides of the base at points above the platform, substantially as and for the purpose specified.

JOHN DOLPH.
